co2 Is It Worth It

Hi wondering is it worth the cost, hassle putting Co2 injection in a 300cm x 150cm x 200cm tent which would have 8 , 20l / 5 gal air pots in under two 1000w hps lights ? any 1 wiv any ideas

If you are able to stop ventilation of the tent for a reasonable period of time without overheating then supplemental CO2 regulated by a PPM controler and environmental controller will increase yield potential.

It can also reduce the time spent in veg. It's a necessity if you want a sealed, air conditioned grow. The co2 itself is relatively cheap, but the equipment required is pricey. Since you seem to be going for big plants, co2 will get you there a lot quicker than without.
